City prepares to host Summer Games for third time

London won its bid to host the 2012 Summer Olympics seven years ago, but there were mixed feelings ahead of the Opening Ceremony over whether the city was ready for the throngs of fans expected at the games.

Signs of road closures and security, by land, air and sea, are all over the city.

"We've ensured that the security is appropriate and proportionate to ensure that we do have a safe and secure games," said Debbie Jevans, of the London Organising Committee of the Olympic and Paralympic Games.

The Department of Transport estimates an additional quarter of a million people will be in London each day of the games. That has the locals feeling squeezed.

"I think security is on people's minds, but I think they're more worried about the inconvenience," said Londoner Sally Cook.

Olympic only lanes are now in effect. Public transportation is the best and sometimes only way to get around the city and to Olympic venues, like the historic Horse Guards Parade, home of beach volleyball.

"It's an awesome stadium, an awesome venue. We're looking forward to the night matches," said U.S. volleyball player Misty May-Treanor.

The Opening Ceremony will take place Friday night at the Olympic Stadium in Olympic Park. To get to the location, fans must pass through several security points with either credentials or a ticket to that day's events.

Security proved effective on Wednesday, when the British Defense Forces scrambled a jet when a commercial plane lost contact with air traffic control. Communication did resume, but it gave people an idea of how quickly Britain is prepared to respond to security risks.
